I help organizations find security weaknesses in AI systems, investigate cyber incidents, recover critical data, and understand what happened when systems or accounts are compromised. My main focus is now offensive AI security and AI red teaming. I test AI systems from an attacker’s perspective to identify how they could be manipulated, exposed, poisoned, or abused before those weaknesses are discovered by someone with malicious intent. AI security services include: ▪ Offensive AI red team assessments ▪ LLM application security testing ▪ Prompt injection and jailbreak testing ▪ System prompt and sensitive data leakage assessment ▪ AI reconnaissance and attack surface mapping ▪ AI agent and tool-use security testing ▪ RAG and vector database security ▪ Adversarial machine learning and model privacy testing ▪ Data and training pipeline security ▪ AI infrastructure and supply chain security ▪ AI security testing, evaluation, and hardening ▪ AI incident response and forensics My offensive AI work is strictly authorized and defensive in purpose. Testing is performed within an agreed scope and clear rules of engagement, with findings translated into practical remediation steps. I also provide digital forensics, DFIR, cyber breach investigation, data recovery, malware analysis, and OSINT investigation. Digital forensics and incident response services include: ▪ Data recovery from computers, drives, mobile devices, and storage media ▪ Forensic investigation of devices, files, accounts, logs, and user activity ▪ Cyber breach investigation and root-cause analysis ▪ Email, cloud, and account compromise investigation ▪ Malware and suspicious-file analysis ▪ Mobile device forensics ▪ OSINT and online investigations ▪ Evidence preservation and forensic analysis ▪ Clear technical reports explaining findings in plain language Tools I work with include: Magnet AXIOM, Cellebrite UFED, Autopsy, FTK Imager, R-Studio, Disk Drill, R-Drive Image, Volatility, Registry Explorer, RegRipper, Wireshark, tcpdump, Zeek, ADB, Linux forensic utilities, security testing tools, and AI security/red teaming frameworks. I can review disk images, memory dumps, mobile backups, cloud exports, email files, logs, AI applications, LLM workflows, AI agents, APIs, RAG systems, and other evidence or environments provided within the agreed scope. I approach every engagement carefully, ethically, and confidentially. I do not promise unsupported conclusions or impossible recovery results. Findings are based on evidence that can be verified. For AI security, the same principle applies: the goal is not simply to find what can be broken, but to understand the risk and make the system safer. I believe AI should serve people, not put them at risk. My work is focused on helping organizations adopt AI securely while protecting users, systems, and sensitive information. If you need help testing an AI system, investigating a cyber incident, analyzing evidence, or recovering important data, I can help you move from uncertainty to clear, actionable findings.
